IMPROVEMENT IN WATER-WHEELS.

Specication forming part of Letters Patent No. l1.2,228, dated August26, 1873; application filed May 13, 1873.

To all whom it may concern:

Be it known that I, ELYMUs HAGKETT, oi Ulysses, in the county of Potterand State of Pennsylvania, have invented a new and useful Improvement inDirect and Reaction Water-Wheels; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawing forming part of this specification, inWhich- Figure l is a top view, partly broken out. Fig. 2 is a centralvertical section, and Fig. 3 is a detail view, of the gate-slide. Fig.4t is a detail bottom view, showing .the relative position of the twocrown-wheels.

The invention relates to modes of utilizing `the reactionary power ofwater; and consists in the meanshereinafter fully described andsubsequently pointed out in the claim.

In the drawing, A is the casing, and B a reaction water-wheel, havingthe buckets C, end-curved at c, and provided with an inl wardly andrearwardly dipping flange, c.

The curve c serves to hold the water from contact with the side ofchutes after the impact, and thereby prevents the water from spendingits force anywhere but on the wheel itself.

By this construction, the impact of water vis first received upon thecurved surface c,

which forms `a vertical cavity, and then thrown back with a reactingforce upon the curved surface c, which forms an oblique cavity that runsout near the hub D, from which the main body G of buckets radiate. Thisserves to utilize, to a great extent, the reactionary force ofthe waterafter striking the wheel, so as to add its impulse in the same directionas that of the direct action.

E is the wheel-shaft, on which rotates the loose hub D, which has theradial buckets that have affixed beneath their discharge ends acrown-wheel, F, that works in a pinion, j', on a shaft, E', to turnmachinery. Of course vthe power may also be applied to machinery throughthe shaft, and in the usual manner. Gr are a series of rigid chutes inwhich work the gates H that regulate the water to be admitted to thebuckets. These gates have lugs h, which Work in guide-grooves a a of thecase. These gates are connectedv by rods I with a rotary disk, J, thatis vibrated in a small arc to adjust the gates. a2 are slots madethrough the casing, and in which the rods I move, their movement beinglimited by the length of the slots, and their direction necessarilycorrespondent thereto.

By this arrangement of the gates, they may be conveniently adjusted inthe chutes, their close proximity to the outer edges of buckets beingalways preserved.

Below the wheel B is a secondary wheel, K, of much less diameter, androtating loosely on the shaft E. It is provided with the series ofbuckets k, curved backward. As the water is thrown from the curvedsurface c of buckets C, the reacting force sends it against the bucketsk, and causes them to rotate the wheel K. This wheel has a crown-wheel,E2, on its periphery that works in a pinion, c, o n the shaft E. Now, inorder to enable this wheel to exert any power upon shaft E', the pinionc must tend to move at a greater velocity than the shaft E would dounder the impulse ofthe wheel B alone. Hence the pinion c is made verysmall, and has but few teeth compared to those of the crown-wheel.

Having thus described my invention, what- I claim as new, and desire tosecure by Letters Patent, is-

l. The buckets G endcurved at c, and provided with an inwardly andrearwardly dipping flange, c', as and for the purpose specified.

2. The backwardly-curved working faces k of wheel K, combined with thefaces c of bucket C, forming an oblique cavity running out near the hubD, as and for the purpose specified.

3. The combination of two water-wheels, one placed above the other, bothrevolving about the same center, and each provided with its owncrownwheel,.of the unequal pinions ef, arranged and operating on thesame shaft E', as and for the purpose set forth.
